So, where did this amazing drink come from? Well, it all started back in the 1920s, when some clever folks discovered that adding malted milk powder to a milkshake created a whole new level of creamy goodness. It was like a match made in heaven, and soon, malt milkshakes were all the rage!
But, what exactly is malted milk powder, you ask? It's basically a mixture of evaporated milk, wheat flour, and maltose, which is a type of sugar that's derived from barley. When you add this magic powder to a milkshake, it's like adding a special ingredient that makes everything taste better!
